Melt the shortening in the microwave. Set aside.
Place in a blender, the chicken broth, red peppers, sweet pepper, cayenne pepper, and garlic powder. Blend on medium speed until vegetables are dissolved in the broth.
Transfer the broth to a large bowl and gradually add the Harina PAN. Stir constantly, with your hands or a wooden spoon, to prevent lumps. Let it stand for 5 minutes. The dough will be thickened.
Add melted vegetable shortening gradually and continue mixing. The mixture should have a smooth consistency, such as peanut butter, If not, add more broth, 1 -2 tablespoon at the time, as necessary. Taste and adjust salt according to your taste. Note: I usually don’t add more salt since the chicken broth add enough saltiness for our taste.
Take one corn husk and place about 1/2 cup of dough in the middle of it. Fold the sides covering the dough and making a kind of a roll. Tie the ends tightly, using kitchen string or raffia, just where the dough ends. Repeat the same procedure until you finish all the dough. You will come out with 14-16 hallaquitas.
Fill 3/4 of a large pot (7-1/4-qt) with water. Add 2 teaspoons of salt, mix to dissolve. Bring to boil over medium heat.
Place the hallaquitas in the boiling water, cover, and cook over medium-low heat for 50-60 minutes, or until the mixture is no longer sticky. To test if the hallaquitas are done: Remove one and try to pull the husk off. If the husk pulls away cleanly from the hallaquita they're done. If the dough is still sticky or wet looking, cook them for 5-10 minutes longer and try again.
Remove tamales from the pot and place them upright in a large colander to drain excess water. Let stand for 15 minutes before serving.
